Use a flow chart template and a simple sink or float method to explore recycling of plastics by density. Great for introducing the concept of recycling as students may differentiate plastics they collect to determine how the plastic should be recycled in their community.
Includes support materials for teaching middle and high school topics and a differentiated lesson plan for grade level 3-5. Includes support information for teaching the properties of plastic polymers, chemical structures, recycling descriptions, and density ranges for each recyclable polymer. Extension activities support age differentiated learning for K-12.
